Boss ?

Three, four, or five blades are most common in marine propellers, although designs which are intended to operate at reduced noise will have more blades. The blades are attached to a boss (hub), which should be as small as the needs of strength allow - with fixed pitch propellers the blades and boss are usually a single casting.

thanks problemchimp I would never have got the boss one

I've been thinking about the final one.

I can't make rocky marble equal tor though!

Sorry it's only half an answer.

I';ve just found a marble that's called a taw ( not sure it's rocky though)

I hope you spot this thread.

A tor is certainly rocky!

Thanks again I got the taw part after you mentioned the dock part
